Re: [U-Boot-Users] Teridian Phy Support tr78q21x3
Hello, I found out, why the Generic MACB MII driver for the AT91SAM9260 doesn´t work. The problem is inside the file /board/atmel/at91sam9260ek/at91sam9260ek.c at91_set_B_periph(AT91_PIN_PA23, 0); //ETX2 at91_set_B_periph(AT91_PIN_PA24, 0); //ETX3 These lines are multiplexed with the TWI Interface of the AT91SAM9260 and on the development board (AT91SAM9260EK) there is an EEPROM connected. Instead of lines PA23 and PA24 you have to use at91_set_B_periph(AT91_PIN_PA10, 0); //ETX2 at91_set_B_periph(AT91_PIN_PA11, 0); //ETX3 which have the same abilites. Then it works perfect ! Is it possible to change this in the official U-Boot tree ? Hopefully someone from denx.de could do that and I hope for a positive reply - Thank you Anatolij Gustschin schrieb: Hello, Manuel Sahm wrote: In the U-Boot 1.3.3 there is already this patch included yes, of course this is already included. I meant you have to _reverse_ this patch (or in other words un-apply it, patch -p1 -R), as it was not included in U-Boot 1.3.0 and as you sad, with U-Boot 1.3.0 ethernet did work. Un-applying this patch and test without it could quickly show if MII mode configuration was your problem. But I see another problem: I uses the AT91SAM9260 microcontroller so I defined in the header: #define CONFIG_AT91SAM9260 1 Instead of the Davicom Phy (RMII), which is used in the DevBoard AT91SAM9260EK I want to use the Teridian Phy(MII), so I write in the header: #undef CONFIG_RMII Now have a look at the patch: +#if defined(CONFIG_AT91CAP9) || defined(CONFIG_AT91SAM9260) || \ + defined(CONFIG_AT91SAM9263) + macb_writel(macb, USRIO, MACB_BIT(CLKEN)); #else macb_writel(macb, USRIO, MACB_BIT(MII)); #endif I don´t go to the line : macb_writel(macb, USRIO, MACB_BIT(MII)); ,because of CONFIG_AT91SAM9260 BUT I have to go there or not ? Probably. If you un-apply the patch, you end up in something like this: #ifdef CONFIG_RMII macb_writel(macb, USRIO, 0); #else macb_writel(macb, USRIO, MACB_BIT(MII)); #endif and this is the macb.c code in U-Boot-1.3.0 (drivers/macb.c:419).

[U-Boot-Users] Teridian Phy Support tr78q21x3
Hello, I?m using a at91sam9260 Microcontroller. I added a Teridian Phy Driver (tr78q21x3) to the Uboot version 1.3.0 It works. (even in linux when I use the linux generic macb driver) If I try to use the latest u-boot-version (1.3.3) with the macb driver - ethernet doesn?t work (in u-boot and linux). I don?t know how to add my phy driver to the latest u-boot version ! Is anybody out there who would be able to insert the phy driver in the latest u-boot version (tree) - I would offer my driver for anybody...
